Wow the load times are waaaaay higher than I remember them being.
Apart from that, quite pleased - I particularly like how every poster or note or even bugle newspaper you can read all the text, which I always try and do in every game and often you cant read everything (which is annoying on a PC game) framerate seems solid too which was a concern
A lot of the mundane creatures look really creepy and cool looking with the update, even the humble bloatfly and mole rat. Even simple things like going to the bed in a house to sleep and noticing detail never saw before like the tiles and trash on the floor looks nice.
Overall, cool update for free but people who dont have the VRAM - you arent missing too much here. Most of the outdoors looks very similar for example.
Some NPC's also have dramatically increased detail like the first minuteman you meet, looking forward to dressing up the female companions.
